foramen spinosum การใช้

• Jacob Winslow is credited with first documenting the existence of the foramen spinosum.
• The foramen spinosum is often used as a landmark in neurosurgery, due to its close relations with other cranial foramina.
• It accompanies the middle meningeal artery and vein as the artery and vein enter the cranium through the foramen spinosum and supplies the dura mater.
• It is pierced by the foramen ovale and foramen spinosum, and at its posterior part is the sphenoidal spine, which is frequently grooved on its medial surface for the chorda tympani nerve.
• The earliest perfect ring-shaped formation of the foramen spinosum was observed in the eighth month after birth and the latest seven years after birth in a developmental study of the foramen rotundum, foramen ovale and foramen spinosum.

• These furrows begin near the foramen spinosum, and the anterior runs forward and upward to the sphenoidal angle of the parietal, where it is sometimes converted into a bony canal; the posterior runs lateralward and backward across the temporal squama and passes on to the parietal near the middle of its lower border.
